This concept of Umtrieb is worth reflecting on, since it refers not to any specific drive such as eros or thanatos, to take Žižek's narrower gloss on the expansive and contractive forces, but to the very structure of drive as a

As such the annular drive conditions all specific drives, and outlines a space for history very different from the "electromagnetic orgasm" that is Martin Wallen's topological figure for the relation between expansive and contractive forces in Schelling's "cosmic history"

In the mean-velocity Doppler model, the blueshift acceleration experienced by the travelling photon is essentially the same contractive gravitational acceleration experienced by the galaxies in the Hubble Flow, so the photon does not experience any gravitational time dilation which differs from the underlying time dilation inherent in the FLRW metric.

But he argues that the West, far from a monolithic bulwark against "diversity," is "the mongrel civilization par excellence"; the systole and diastole of contractive monoculturalism and expansive multiculturalism are its heartbeat.
